- What is a knowledge cutoff, and how does it affect an LLM's answers?
The cutoff is the point after which the training data contains nothing, so the model does not know later events unless they are given in the prompt or fetched by a tool. It may also answer confidently as if the world stopped at that date.
BeginnerQuick answer1 min read - How do you make a RAG system cite its sources?
Store a source id with every chunk, pass the chunks to the model with labels, and instruct it to cite the labels it used. Then check in code that each cited id was actually retrieved and ideally that the claim is supported by that chunk.
